** Tailback Marc Tyler did not practice after spraining his left ankle late in the Arizona State game. But he did some running on the side and said he should be fine for Saturday's trip to Arizona. Tyler added that the rod that's in his leg from a high school injury might have prevented him from breaking his ankle.

** Receiver Robert Woods was listed as limited on the injury report but did very little work. Woods played sparingly against Arizona State because of a back injury and an illness.

** Others who did not practice included DT Hebron Fangupo, SS Jawanza Starling, OT Matt Kalil, OL Abe Markowitz and TE Blake Ayles. OT Tyron Smith and CB Brian Baucham were limited. Kalil appeared to sprain an ankle early against ASU but remained in the game.

** Receiver Markeith Ambles and linebacker-fullback Simione Vehikite, who had been suspended for off-the-field issues, were reinstated and returned to practice.

Here's what USC coach Lane Kiffin had to say about the suspensions being served by freshman receiver Markeith Ambles and redshirt-freshman linebacker Simione Vehikite:

“We have extremely high standards for our players as student-athletes. Markeith wasn't meeting those, so he's been suspended indefinitely. With all our suspensions, we give them academic help downstairs with our tutors. If you're not going to come here to be a student-athlete, you should go somewhere else. We're not going to let kids come here and not take a serious approach toward academics and just think they can play football.

“The suspensions that have happened -- going back to Simi, Patrick Hall and now Markeith -- have all been all young kids that didn't understand our expectation level. None of it has to do with anything with the law or anything criminal, anything big. It's simply not meeting our expectations.

“What your hope is (is) that it serves as a wake-up call, that they understand the importance of something as special as a scholarship to USC. It can be taken away. You hope that they respond to it. Patrick Hall did, Simi is going down the right track so far, and we hope Markeith does as well.”
